In April 2006 the elite 3 Para Battle Group was despatched to Helmand Province on a tour that has become a legend. All that summer the Paras were subjected to relentless attacks. Two years later the Paras are back. The enemy has been forced to adopt new weaponry and tactics. But how much progress are we really making in the war against the insurgents? And is there an end in sight? In this searing account of 3 Para's return,

The West is in shock. Al-Qaeda has struck the US on 9/11, and thousands are dead. Within weeks, UK Special Forces enter the fray in Afghanistan alongside the CIA's Team Alpha and US troops. Victory is swift but fragile. Hundreds of jihadists surrender, and two operatives from Team Alpha enter Qala-i Jangi - the 'Fort of War' - to interrogate them. The prisoners revolt; one CIA man falls, and the other is trapped inside the fort. Seven members of the SBS - elite British Special Forces - volunteer for the rescue force and race into danger and the unknown.

Summer 2006, Afghanistan: an apparently deserted village, and a rapidly ticking clock... The relentless Taliban ambush which followed saw several British soldiers dead, two armoured vehicles destroyed - and Corporal of Horse Michael Flynn awarded an MC to go alongside his Conspicuous Gallantry Cross. Mick Flynn has never backed away from a challenge.

Almost 2.5 million Americans have served in Afghanistan or Iraq since September 11, 2001. C.J. Chivers has reported from both fronts from the beginning, walking side by side with combatants for more than a dozen years. He describes the experience of war today as it is endured by those most at risk - the camaraderie and profound sense of purpose, alongside courage, frustration, and moral confusion mixed with technical precision. In these remote places where the reason for their presence is sometimes not clear, these young men kill or are killed, facing palpable and often constant threat of ambush or hidden bombs....

In Helmand province in July 2006, Major Adam Jowett was given command of Easy Company, a hastily assembled and understrength unit of Paras and Royal Irish rangers. Their mission was to hold the District Centre of Musa Qala at any cost. Easy Company found themselves in a ramshackle compound, cut off and heavily outnumbered by the Taliban in the town.

In July 2009 Geraint (Gez) Jones was sitting in Camp Bastion, Afghanistan, with the rest of The Firm - Danny, Jay, Toby and Jake, his four closest friends, all junior NCOs and combat-hardened infantrymen. Thanks to the mangled remains of a Jackal vehicle left tactlessly outside their tent, IEDs were never far from their mind. Within days they’d be on the ground in Musa Qala with the rest of 3 Platoon - a mixed bunch of men Gez would die for.  

At 24 years of age, U.S. Army Ranger Sean Parnell was named commander of a forty-man elite infantry platoon - a unit that came to be known as the Outlaws - and was tasked with rooting out Pakistan-based insurgents from a mountain valley along Afghanistan's eastern frontier. Parnell and his men assumed they would be facing a ragtag bunch of civilians, but in May 2006 what started out as a routine patrol through the lower mountains of the Hindu Kush became a brutal ambush.

Rob Driscoll, former sergeant with 42 Commando, Royal Marines, served tours in Iraq, Kuwait and Kosovo. A born leader of fighting men, with the medals to prove it, he also endured three tours in Afghanistan. The third of those will go down in history as one of the UK military's darkest hours, for it marked the first time a British serviceman has been tried for a murder on the battlefield since the Second World War.

Kim Hughes is the most highly decorated bomb disposal operator serving in the British Army. He was awarded the George Cross in 2009 following a gruelling six-month tour of duty in Afghanistan, during which he defused 119 improvised explosive devices, survived numerous Taliban ambushes and endured a close encounter with the Secretary of State for Defence.

From its early beginnings in World War II, the Special Air Service (SAS) has won renown in some of the most dramatic, dangerous and controversial military special operations of the 20th century. It is a secretive and mysterious unit, whose operations and internal structures are hidden from the public eye. Now, one of its longest-serving veterans offers a glimpse into the shadowy world of the SAS. Rusty Firmin spent an incredible 15 years with 'The Regiment' and was a key figure in the assault of the Iranian Embassy in London in May 1980. 

In April 2006, the elite 3 Para battlegroup was dispatched to Helmand Province in southern Afghanistan. They were tasked with providing security to reconstruction efforts, a deployment it was hoped would pass off without a shot being fired. In fact, over the six months they were there, the 3 Para battle group saw near continuous combat, one gruelling battle after another, in what would become one of the most extraordinary campaigns ever fought by British troops.

April 2004: Dan Mills and his platoon of snipers flew into Southern Iraq, part of an infantry battalion sent to win hearts and minds. They were soon fighting for their lives. Back home we were told they were peacekeeping. But there was no peace to keep. Because within days of arriving in theatre, Mills and his men were caught up in the longest, most sustained firefight British troops had faced for over 50 years.

What makes an ordinary but highly educated Englishman, with no previous military training, decide to travel and fight in one of the most brutal conflicts on the planet? Desert Sniper is an extraordinary true account of one man's journey from well-meaning volunteer to battle-scarred combat sniper, placing himself daily in the line of fire to fight one of the greatest evils of this new century.

It takes a tough mind-set to be a successful sniper, to be able to dig in for days on your own as you wait for your target, to stay calm on a battlefield when you yourself have become the target the enemy most wants to take out. Craig Harrison has what it takes, and in November 2009 in Afghanistan, under intense pressure, he saved the lives of his comrades with the longest confirmed sniper kill - 2,475 metres, the length of 25 football pitches.

The No. 1 Sunday Times bestselling modern classic: A Bravo Two Zero for the Second Gulf War. They were branded as cowards and accused of being the British Special Forces Squadron that ran away from the Iraqis. But nothing could be further from the truth. Ten years on, the story of these sixty men can finally be told. In March 2003 M Squadron - an SBS unit with SAS embeds - was sent 1,000 kilometres behind enemy lines on a true mission impossible, to take the surrender of the 100,000-strong Iraqi Army 5th Corps.
